Friedrich II said:Well, the Duke of Meath was supposedly Mael Ui Mórdha (O'Moore). As mentioned above, he died in 1086. the Mórdhas came from Ulster and migrated south through Meath and even into Leinster. they should be able to spawn in leinster, osraige, mide, dublin, and ulaid. I believe his father's name was Gairbhith, and he died in 1061.
The person who could best be called Count of Osraige was Finn Ui Caollaidhe (O'Kealy), who died in 1098.
I think the Count of Mide was Conchobhar Ua Maoileachlainn (Mac Laughlin). who died in 1068 and succeeded by his son Domhnall of the same dynasty.
Damn your good! I'd like to think that I know my Irish history pretty well(at least for an American) but I wouldn't even know where to pull that information from. I tried to go a Google search for family histories and such but had no luck, and my history books wouldn't have had that info either. Good job!
